Embodiment Construction
[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.
[0020] The present invention provides a tire pressure monitoring device based on OBD II, comprising:
[0021] OBD II data acquisition module, tire pressure detection module, processing module and alarm module. The OBD II data acquisition module is used to collect and send all the wheel speed values during vehicle operation and the fuel consumption value of the vehicle in the predetermined distance; the tire pressure detection module is used to detect and send the tire pressure value; the alarm module is used to detect Early warning prompts when the tire pressure is insufficient; the fuel volume limit and tire pressure limit are set on the processing module; the processing module receives all wheel speed values and fuel consumption values transmitted by the OBD II data a...

The invention discloses an OBD II-based tire pressure monitoring device, comprising: an OBD II data collection module, which is used to collect and send the rotational speed values of all wheels in the running of the vehicle and the fuel consumption value of the vehicle in a predetermined distance; The pressure detection module is installed on any wheel of the vehicle, and the tire pressure detection module is used to detect and send the tire pressure value of the vehicle; the alarm module; the processing module, which is set with the oil quantity limit and the tire pressure limit; the processing module Receive all wheel speed values and fuel consumption values transmitted by the OBD II data acquisition module. The invention aims at the defects existing in the current automobile tire pressure detection, and monitors the tire pressure status in real time by detecting the rotation speed of the wheel and the fuel consumption. The invention not only can accurately detect the tire pressure, but also saves the cost.
Description
technical field [0001] The invention relates to an OBD II-based tire pressure monitoring device. Background technique [0002] When the tire pressure is 30% higher or lower than the standard tire pressure, the fuel consumption will increase significantly; when the tire pressure is 35% lower than the standard tire pressure, the fuel consumption per 100 kilometers will increase by 1-3 liters; the less the air pressure, the more the fuel consumption will increase. Secondly, if the car runs for a long time under the condition that the tire pressure does not meet the standard, the speed of tire wear and damage will be 2 times or even 3 times that of the tire with the pressure meeting the standard, thus seriously affecting the economy. Therefore, tire pressure monitoring is of great significance to improving driving safety, reducing fuel consumption and reducing tire wear. [0003] Tire pressure monitoring devices currently used in the world can be divided into two categories: di...
